초록
TiC powders were successfully synthesized by carbothermal reduction of Ti-O-C precursor in argon at 1,400 °C for 2 h. Andthe Ti-O-C precursor was formed by sol-gel method using titanium butyrate (Ti(OC4H9)4), fructose (C6H12O6), and acetylacetone (acac). Here, acac was used as chemical modifier to control Ti(OC4H9)4 hydrolysis to obtain stable sol. Furthermore,TG-DSC, XRD, FTIR, Raman, SEM, and EDS were employed to characterize the precursor and TiC powders. Moreover, acacas stabilizer was studied using FTIR when reacted with Ti(OC4H9)4 formed stable six-member ring as a result of the existenceof tautomer, prevent the nucleophilic attack of water, which reduced the hydrolysis rate of Ti(OC4H9)4. Besides, the compositionof TiC phase was further understood by the Raman spectra, and the results showed that the peaks at 403 cm−1, 513 cm−1, and 629 cm−1 were ascribed to the characteristic peaks of TiC. Finally, the photomicrograph revealed an equiaxed shape and theaverage grain size of TiC particles was ca. 1 um. The EDS indicated that the particles contain elements of Ti and carbonaccording to dot and line scan.
